Abstract
(DE)
Erzeugung von Gläsern oder anderen Nanopartikel enthaltenden dielektrischen Materialien mit geänderter Farb- und Polarisationswirkung bis zur völligen Transparenz unter Beibehaltung einer ebenen optischen Oberfläche. Ein Dielektikum mit ionischer Leitfähigkeit, welches in der Oberflächenschicht Nanopartikel enthält, wird einem hohen elektrischen Feld und gleichzeitig einer erhöhten Temperatur ausgesetzt. Einsatz als farbselektive Filter, Polarisatoren.
(EN)
The invention relates to a method for dissolving metal nanoparticles in dielectric materials under the effect of a DC field. The invention also relates to a method for producing dielectric materials that contain glasses or other nanoparticles and that have modified color and polarization effect up to complete transparency while maintaining a level optical surface. According to said method, a dielectric material that has ion conductivity and that contains nanoparticles in its surface layer is subjected to a strong electrical field and at the same time to an increased temperature. The inventive material can be used as color-selective filter or polarizer.
(FR)
L'invention concerne un procédé pour dissoudre des nanoparticules de métal dans des diélectriques sous l'effet d'un champ électrique continu. Cette invention concerne également la production de verres ou d'autres matériaux diélectriques contenant des nanoparticules, dont l'effet de polarisation ou de couleur est modifié jusqu'à la transparence totale tout en maintenant une surface optique plane. Selon ledit procédé, un diélectrique à conductivité ionique, contenant des nanoparticules dans sa couche superficielle, est exposé à un champ électrique élevé et, simultanément, à une température accrue. Ladite invention concerne en outre l'utilisation desdits matériaux comme filtres sélectifs en couleur ou comme polariseurs.
